Key calibration function eliminates manual potentiometer adjustment, enabling quick setup and consistent results. Onboard MCU reads data from the infrared probe and outputs both digital and analog signals for flexible integration with your controller. Supports I2C and serial communication, compatible with a variety of control schemes. Includes standard IO interface and PH2.0 connector for easy wiring. Integrated with 8 sensitivity infrared sensors to rapidly detect the contrast between black and white lines for reliable line detection. Typical use scenarios Linefollowing robot and educational robotics projects: provides straightforward calibration, multischeme communication, and fast line detection to improve responsiveness and learning outcomes. Small conveyor or automated alignment tasks: use the line contrast sensing to identify position or edge markers and synchronize downstream processes. Prototyping and data gathering in research or development: capture line contrast data with the MCU and analyze digitally or in analog form for experiments.
